I feel dizzy and black as soon as I stand up

As the saying goes: "It is better to sit than to stand, and it is better to lie down than to sit". I believe everyone knows that lying down is a comfortable thing. However, lying down is not something that makes everyone comfortable. Some people will feel dizzy and have black eyes when they stand up from lying down. This greatly affects their life. It is necessary to understand the cause and adjust it in time. So let me introduce why you feel dizzy and have black eyes when you stand up from lying down?

This condition is caused by insufficient blood supply to the brain due to sudden changes in body position.

Guidance:

If this situation occurs frequently, it is recommended to go to the hospital to check blood pressure and blood routine to see if there is low blood pressure and anemia. If everything is normal, then just be careful not to do this movement too quickly. Just pay attention to your daily life, get enough sleep and eat a balanced diet.

When you stand up after waking up, sitting or squatting for a long time, you may suddenly feel dizzy. In mild cases, you may only be dizzy for a few seconds before recovering, but in severe cases, you may become severely dizzy and lose consciousness, causing you to fall and potentially cause brain or body injuries.

This condition is medically known as "postural hypotension." Why is it that some people can stand up easily without any difficulty, while others may suffer physical discomfort or even injury? In fact, this is related to your physical health. As long as your body circulation is good, this situation will not easily occur. As for those who already have postural hypotension, there is no need to be too nervous. As long as they develop the habit of not changing positions immediately, they can avoid discomfort or injury.

Understanding postural hypotension

Causes of postural hypotension

When we want to change from lying, sitting or squatting to standing up, the posture looks simple, but it requires the coordination and cooperation of various organs of the body, including the heart, blood vessels, nerves, etc., to accomplish the task of standing up smoothly.

When the body wants to stand up, the heart must deliver enough blood through the blood vessels to the brain, which is located at the highest point. At this time, the blood vessels must be coordinated by the nervous system to appropriately reduce their diameter so that the blood can be delivered higher and farther. However, if these organs react too slowly or are unable to perform this function, the brain will experience temporary hypoxia, causing dizziness or fainting, which is called "postural hypotension."

Good target

Although postural hypotension is not a highly contagious disease like the common cold, according to clinical observations by doctors, more than half of the people in the country have experienced postural hypotension, with women being the majority. If divided by age, the elderly have more than the young, and the others are pregnant women.
